Acoustic and heat insulation values do not only depend in materials properties but also in the design solution. It is important to integrate the properties discussed in our deign to improve the insulation of the panels because possible mistakes will reduce the calculated insulation properties of the material. Sound leaks, like water leaks, must be prevented because sound will travel through any size opening with little loss
Gaps and cracks have negative influence in the total sound insulation of a structure. Rigid connections are needed to avoid reduction. Coupling1 between leafs and flanking sound transmission2 can also reduce the sound insulation of a cavity construction, and must taken seriously into concern.
• Sound leak at intersection of masonry wall and ceiling
• Sound leak at edge joint (due to deflection of floor slab and lack of sealant)
Heat resistance can also have big losses because of poor design and detailing. In thermal bridges the level of heat resistance is much lower.
- This blog is about research on papercrete as part of my graduation project.
Papercrete is an experimental material which replaces some amount of cement with paper pulp in the mix. There is no information about its structural behavior and durability, that why its use remains limited. The goal is to bring papercrete closer to standardization.
Good design idea will be the one which combine all the materials properties, low price – lightweight – flexibility -surface texture. Papercrete facade panels have the potential to be competitive to the market.
